Hiffman Releases Q1 2026 Industrial Big Box Report
NAI Hiffman is pleased to present the Q1 2026 Big Box report, our firm’s in-depth look at statistics for industrial big box inventory in the Chicago metropolitan area.
Vacancy Improves While Construction Activity Rises

Construction


- Total active big-box construction reached 11.9 million square feet, representing a 34.1% decrease year-over-year, with speculative projects accounting for 52.4% of activity.
- New big-box developments gained momentum in Q1, with several projects breaking ground and signaling renewed developer confidence in targeted submarkets.
- The I-55 Corridor and Northwest Indiana each led construction activity with 2.3 million square feet underway, followed by the I-80/Joliet Corridor with 1.8 million square feet.
- The largest project currently under construction is a 1.2 million-square-foot speculative facility being developed by DHL in Plainfield, which was pre-leased by RJW Logistics in late 2025.
- Market fundamentals remain solid as demand for modern big-box facilities continues to be driven by third-party logistics providers, e-commerce operators, manufacturing growth, and onshoring activity, particularly in the I-80 Corridor where large-block availability is limited.
